No, It is not possible to have a quadrilatera with four acute angles because the addition of four angles for quadrilateral = 360 & acute angle is less than 90 degree
A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
A rhombus has 2 opposite acute angles and 2 opposite obtuse angles
Yes a kite can. See related link.
Yes.
There can be 4 different acute angles in an irregular 4 sided quadrilateral that all add up to 360 degrees.
